EYEGLASS GUARD.

Application filed May 23, 1923. Serial 1T0. 640,844. 1

To all whom it may concern:

Be it known that I, WILLIAM H. BOUTELLE, a citizen of the United States, residing at Sturbridge, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Eyeglass Guards, of which the following is a specification.

This invention relates to improvements in eyeglass guards and a method of producing same,and has particular reference to guard pads having a composition covering for their faces. 1

Prior to my invention guard pads have been made with a metal backing, to the face of which is secured, by rivets, a piece of compositionmaterial. The metal pins or rivets appearing in the face of the pad are attacked chemically by'perspiration when warm, this chemical action rendering the pad unsanitary and disagreeable in appearance.

One object of'the present invention is to produce an eyeglass guard pad having a composition face without any metallic attaching parts.

Another object is to provide a guard pad of improved construction whereby the use of small pins or rivets ,is dispensed-with, and the cost of manufacture-will be lessened.

A further object is to provide an improved method of assembling such pads.

Other objects and advantages will be ap-- parent from the. following-description taken in connection with the accompanying drawings, wherein are shown preferred embodiments of the invention.

In the drawings:

. Figure 1 is a front elevation of an eyeglass embodying the invention. igure 2 is an elevation of the uard.

Figure 3- is a rear elevation of t e guard pad illustrating the method of connecting it v modification wherein the metal plate 181s to the guard.

Figure 4 is a vertical transverse sectional view on the line 44'of Figure 3. I Figure 5 is a detail perspective view 0 one of theelements of the improved pad.

Figure 6 isa similar view of the metallic core.

Figure 7 is a similar view of the'outer composition cover.

Figures 8 and 9 are views similar to Figure 4' illustrating modifications.

Similar reference characters designate 18 is receivable and the stud 19 corresponding parts throughout the several views.

-I have illustrated my improved pad as applied to a fingerpiece mounting, which comprises theusual bridge 10 carrying at each end thereof a lens 11, and adjacent each end the usual pivot post 12. the pivot post 12 is the usual fingerpiece 13 carrying at its inner extremity the guard 14:, said guard being provided at its upper side with an offset arm 15 having at its extremity a head 16.

The numeral 17 designates the pad, generally said pad being composed of a metal plate 18 having on one surface a stud 19 which is receivable in an aperture in the head 16 of the guard, and riveted over as indicated at 20. The union between the guard and the pad is quite loose, such that the pad will be able to move in relation to the guard so as to readily conform to the shape of the wearers nose. A composition disc 21 having a central aperture 22 is mounted upon the plate 18 with the stud 19 extending through the aperture. The eripheral edges of the plate 21 may be 0 set as clearly shown in Figure 4, and a second composition plate 23 may be applied to the outer face of the plate 18. The plates 23 and 21 are then cemented together as at 24, whereby: the metal plate 18 is completely covered by a composition material and no 25 if desired.

In Figure 8 I have shown a modification wherein the inner composition cover 27 is provided with a recess 26, wherein the plate projecting beyond the plate27 as illustrated.

Figure 9 is a representation of another @cemented to the sheet 28, as shown at 24.

From the foregoing description it will be readily apparent that'-I have produced an improved guard for eyeglasses wherein no metallic parts willtouch the face and, therefore, the pad will be" very sanitary and durable. I have provideda novel method of assemblin such articles whereby the cost of assembly is greatly reduced and the use of expensive dies and small rivets is eliminated. Obviously changes may be resorted to in the form and arrangement of parts, and I reserve the right to make such changes falling within the scope of the appended claims Without departing from the spirit of my invention. v

Having thus described my invention, what I claim is: 1 l v 1. In a guard for-an ophthalmic mounting, a metallic face plate with an offset stud, a non-metallic facing on the front of the 'metallic face plate extending beyond the edges thereof, a non-metallic facing on the back of the metallic face plate having a portion covering the back face of the face plate around the offset stud, and a portion extending beyond the edges of the face plate and engaging the front non-metallic facing beyond the edges of the metallic face plate, and cementitious means for uniting the front and back non-metallic facings.

2. In a guard for an ophthalmic mount ing, a metallic face plate With an offset stud, a composition facing .on the front of the metallic face plate extending beyond the edges thereof, a composition facing on the back-of the metallic face plate having a portion covering the back face of the metallic face plate around the offset stud, a portion extending beyond the edges of the metallic face plate, and engaging the front composition facing beyondthe edges of the metallic face plate, and cementitious means for uniting the composition members together. WILLIAM H. BOUTELLE.
